I remember watching some of the older WSOP broadcasts on ESPN Classic.. I swear I saw players table their hand when deciding whether or not to call an all-in when heads-up in a pot. The announcers were never shocked by it. ("Now he's exposing his hand, we see he has the top pair with a weak kicker, he's trying to figure out if it's the best hand.")

Did this practice change in the past 5-10 years?
